2020-2025 GM 3.0L DURAMAX Crankcase Ventilation Oil/Water Separation Kit

Crankcase Ventilation Oil/Water Separation Kit - GM 3.0L Duramax 2020-2025 LM2 LZ0

During the development of our PPE 3.0L Duramax Intercooler and Turbo Resonator Delete Tube, we confirmed that these trucks emit a significant amount of oil and hydrocarbons through the crankcase ventilation system, which are directly routed back into the turbo compressor housing. These contaminants mix with EGR gases, causing harmful sticky carbon buildup in the plastic intake manifold, swirl valves, and intake valves. This leads to reduced performance, poor fuel economy, higher EGTs, cylinder compression loss, increased emissions, and potential damage to engine components.

The PPE Oil Catch Can Kit is designed to combat these issues effectively. Key features include molded, oil-resistant, one-inch-diameter PCV hoses and a highly efficient stainless steel filter screen, which removes oil and water vapor exiting the PCV valve. The long, one-inch hoses reduce the velocity of the mixture passing through the system, allowing the oil/water vapor to condense out of the mixture. This removal prevents nasty carbon buildup, ensuring your engine components remain clean and efficient. The kit also includes an additional aluminum oil reservoir, specially shaped to fit snugly in the tight space above the fender liner where it’s installed.

The PPE Oil Catch Can Kit has been extensively tested and proven under various weather conditions. Protect the longevity and performance of your 3.0L Duramax engine with this bolt-on upgrade.

Fitment Note: This kit is not compatible with 2022-2025 GMC Sierra trucks. We are currently developing a new kit specifically designed for these models, which will be released soon.
